Now I am enclosing the scan of the 12th edition, published in 1982, which is dominated by the Karpov-Korchnoi matches (although it does not include any reference to the games of the match in Meran). This volume was the final one in the series in descriptive notation, and one notable innovation in it was the inclusion of some world championship caliber games in the notes!The scan is my own, and it was done from an original in bad shape, at a time when I knew very little about scanning. So the product is technically poor, but it is a fine collector's item, all the same. [/I]
